Canonical: Use `get_the_terms()` to verify that a post belongs to the requested `%category%`.
The `get_the_terms()` wrapper provides cache support, and saves a database hit on sites with a persistent cache backend. Props spacedmonkey. Fixes #36602. git-svn-id: https://develop.svn.wordpress.org/trunk@37262 602fd350-edb4-49c9-b593-d223f7449a82
